Abstract

Abstract A FRAME MEMBER HAS SPACED SIDE WALLS JOINED BY A BOTTOM WALL TO FORM A GENERALLY U-SHAPED CROSS-SECTION, THE EXTREMITIES OF THE SIDE WALLS BEING FORMED WITH INWARDLY PROJECTING FLANGE PORTIONS PARTIALLY OVERLYING THE BOTTOM WALL. A HOLLOW CLAMPING MEMBER IS RECEIVED WITHIN THE FRAME MEMBER RESTING AGAINST THE FRAME MEMBER BOTTOM WALL WITH CLAMPING MEMBER SIDE WALLS EXTENDING ADJACENT THE SIDE WALL FLANGE PORTIONS OF THE FRAME MEMBER AND A TOP WALL OF THE CLAMPING MEMBER OUTWARDLY OF THE FRAME MEMBER. THUS, WITH DEFORMABLE SHEET MATERIAL INSERTED WITHIN THE FRAME MEMBER, BETWEEN ONE OF THE FRAME MEMBER SIDE WALLS AND ITS CORRESPONDING CLAMPING MEMBER SIDE WALL, AND WITH DOWNWARD DEFORMING PRESSURE APPLIED TO THE CLAMPING MEMBER TOP WALL, THE CLAMPING MEMBER IS TRANSVERSELY DEFORMED FORCING THE CLAMPING MEMBER SIDE WALL TO CLAMP TRANSVERSELY AGAINST THE FRAME MEMBER SIDE WALLS AND OUTWARDLY AGAINST THE SIDE WALL FLANGE PORTIONS OF THE CLAMPING MEMBER CORRESPONDING CLAMPING THE DEFORMABLE SHEET MATERIAL THEREBETWEEN. IN ONE FORM OF THE CLAMPING MEMBER, AN INVERTED, U-SHAPED CROSS-SECTION CONFIGURATION COOPERATES WITH AN UPWARD PROTRUSION OF THE FRAME MEMBER BOTTOM WALL TO ACCOMPLISH THE CLAMPING, AND IN ANOTHER FORM THE CLAMPING MEMBER IS ANNULAR IN CROSSSECTION FOR ACCOMPLISHING THE CLAMPING.
